Just some advice, I would go ahead and top the two big plants. Either pinch off the top with your fingers or cut it with some scissors. The more you top them the shorter they will grow. Looking great so far. I had one of those buckets once. The pump vibrated so much I could hear it when I was laying in the bed every night trying to go to sleep. And, I live in a condo that's attached on two sides to other condos. And, I'm sure they could hear it too. So, I got rid of it and stayed with soil. It was in the attic and that amplified the vibrations.
